1. Divide the numerator by the denominator to get a decimal.
2. Multiply the decimal by 100 to get the percentage.

### Conversion Steps

1. [tex]\(\frac{7}{20}\)[/tex]:
- Compute the decimal: [tex]\( \frac{7}{20} = 0.35 \)[/tex]
- Convert to percentage: [tex]\( 0.35 \times 100 = 35\% \)[/tex]

2. [tex]\(\frac{13}{5}\)[/tex]:
- Compute the decimal: [tex]\( \frac{13}{5} = 2.6 \)[/tex]
- Convert to percentage: [tex]\( 2.6 \times 100 = 260\% \)[/tex]

3. [tex]\(\frac{1}{2}\)[/tex]:
- Compute the decimal: [tex]\( \frac{1}{2} = 0.5 \)[/tex]
- Convert to percentage: [tex]\( 0.5 \times 100 = 50\% \)[/tex]

4. [tex]\(\frac{9}{25}\)[/tex]:
- Compute the decimal: [tex]\( \frac{9}{25} = 0.36 \)[/tex]
- Convert to percentage: [tex]\( 0.36 \times 100 = 36\% \)[/tex]

5. [tex]\(\frac{21}{50}\)[/tex]:
- Compute the decimal: [tex]\( \frac{21}{50} = 0.42 \)[/tex]
- Convert to percentage: [tex]\( 0.42 \times 100 = 42\% \)[/tex]

### Summary of Results

- [tex]\(\frac{7}{20} \rightarrow 35\%\)[/tex]
- [tex]\(\frac{13}{5} \rightarrow 260\%\)[/tex]
- [tex]\(\frac{1}{2} \rightarrow 50\%\)[/tex]
- [tex]\(\frac{9}{25} \rightarrow 36\%\)[/tex]
